STOPPER-EXTRACTDR,

Speccatison of Letters Patent.

Patented Mar. 26, 1918..

Application led November 14, 1917. Serial No. 201,999.

To all whom it may concern:

Be it known that I, ALBnRrW. KELIN, a citizen of the United States, residing at N. S. Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Stopper-Extractors, of which the following is a specification, reference being had to the accompanying drawings.

rIhis invention relates to certain improvements in stopper extractors and has relation more particularly to a device of this general character especially designed and adapted for use in connection with ber disks employed with milk bottles or thelike, and it is an object of the invention to provide a novel and improved extractor which may be readily vand conveniently engaged with the disk and which also serves to facilitate the removal or application of the disk until the bottle or the like is emptied of its contents.

Another object of the invention t is to provide a novel and improved device of this general character which includes a head adapted to pierce the disk together with means co-acting with said head to clamp the disk after the same has been pierced and which also serves to close the opening affected by the piercing of the disk so that vitiated air or foreign substances are prevented from entering within the bottle in the event the disk should be again applied after being once removed.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved stopper extractor wherein certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order thatmy invention may be the better understood I will now proceed to describe the same with reference to the accompanying drawings wherein:

Figure lis a view partly in section and partly in elevation of a stopper extractor constructed in accordance with an embodiment of my invention, a co-acting cap being .indicated by dotted lines; and

Fig. 2 -is a sectional view taken substantially on the line 2 2 of Fig. 1 and in the direction of the arrow.

As disclosed in the accompanying drawings 1 denotes a head or knob of predetermined coniguration and dimension and provided in its innerface with the recess or socket 2. 3 denotes an elongated shank extending within the socket 2 at substantially the longitudinal center thereof and provided with a threaded extremity engageable within the handle or knob 1 whereby said shank 8 and knob 1 are arranged in assembled relation. The shank 3 is of a length to extend beyond the open end of the recess or socket 2 and the outer end of said shank is provided with a spear head 4 adapted to be forced through a bottle cap of a type generally employed for sealing milk bottles or the like.

The shank 3 is loosely disposed through the axial center of a clamping and sealing plate 5 and said plate 5 is constantl urged toward the head 4 through the me ium of the expansible member 6. As herein embodied the expansible member 6 consists of a spiral spring encircling the shank 3 and interposed between the plate 5 and the base or bottom of the recess or socket 2.

After the head 4 has been forced through a cap the shank is given a quarter turn so that the head cannot be withdrawn through the opening produced in the cap. The expansible member 6 serves to cause the plate 5 to clamp the disk between the plate and the inner end portion of the head 4. The plate 5 is of a diameter in excess of the major diameter of the head 4 and therefore engages the cap in such a manner as to prevent vitiated air or foreign substances to pass through the opening produced in the cap by the head 4 and which is of particular advantage when the cap has been used to seal the bottle after the cap has been once removed.

My improved extractor is adapted to be maintained in engagement with the capi until after the bottle or the like with which the cap co-acts has been completely emptied of its contents and by having the plate 5 substantially seal the openin produced in the cap by the head 4 it will e at once understood that the contents of the bottle or the like, particularly when in a refrigerator Yention is particularly Well adapted for use by reason of the convenience and facility with which it may bev assembled andl operated and it will also be:obviousI that myinvention is susceptible of some change and modification Without materially departing from` the principles and: spirit thereof, and for this reason I donot Wish to be understood as limiting myself to lthe precise arrangement and formation ofthe several parts herein shownl in carrying out -my invention in practice except as hereinafter claimed;
